Could you tell me what are bilateral colobomas and how are they affecting my daughter?

Eye Issue: Colobomas occur in the eye (in the lens or retina). They can have little impact to significant impact on vision and eye development, depending on their size and other factors. I would highly recommend you ask this question to your child's physician as it depends on their individual case. And please seek answers quickly if you are concerned of a new or worsening problem.
